Patent GB-1109153-A (GB)
Title: Improvements in or relating to apparatus for inserting articles in cartons
Inventor: JACKSON ERIC
IPC: B65B23/08
Filed: 1964-03-13
Abstract: 1,109,153. Collectively packaging separate articles; suction lifting devices. REED CARTONS Ltd. 15 March, 1965 [13 March, 1964], No. 10792/64. Headings B8C and B8H. Apparatus for filling compartmented cartons has means for conveying cartons and articles to a filling station where a plurality of suction pumps pick up the articles individually, transfer them into alignment with the carton compartments and then push the articles into the compartments. Empty erected egg cartons are fed intermittently by means of a conveyer with pushers between a pair of guide rails 24 to a first filling station shown in the Figure, while trays 94 filled with eggs 96 are supplied from a delivery apparatus 12. The egg cartons arrive at the filling station in pairs one behind the other and are fed along a track 40 by means of a pusher 41 mounted on conveyer chains 6, their movement being temporarily halted when they are in a position for receiving eggs. The trays 94 are fed into the filling station on a conveyer 73 until the leading row of eggs is in the position for being transferred when the conveyer is stopped. The leading row of eggs are now lifted up by a suction transfer device (as shown in Specification 1,109,152 see Division B8 except for Fig. 13) which is pivoted at 110 to a pair of arms 108 which rotate about a shaft 65 between the two broken line positions shown, so that the transfer device oscillates between the tray and the carton for transferring the eggs. The transferred row of eggs fill the left-hand side of the carton as seen, after which the carton is transferred to a second similar filling station and the tray is moved so that a subsequent row of eggs are in a position for being transferred into the next pair of following cartons. In the second filling station the cartons are filled with a second row of eggs in the same manner as at the first station. A set of dependent fingers 97 (not shown) sense any eggs which have been left on a tray and in that event operate a microswitch to stop the apparatus. A pivoted arm 44 (not shown) senses a correctly assembled pair of cartons being fed into the filling station to initiate filling. On leaving the second filling station the filled cartons are delivered on to a platform for removal. The timing and operations for transferring the eggs, trays and cartons are controlled by a series of cams, chains and gears.

Filed: 1923-04-26
Abstract: 198,347. Akt.-Ges. Brown, Boveri, et Cie. May 26, 1922, [Convention date]. Vapour apparatus, arrangements of.-A system for the automatic connection of an installation equipped with large mercury-vapour rectifiers comprises a series of switches which are actuated in dependence upon one another and upon time. On closing the main switch S, to connect the primary winding of the transformer T to the alternating-current net N, an auxiliary switch S1<SP>1> connects a time relay P1 to an auxiliary net NH. After an interval, the relay P1 closes a switch Q1 and connects relay R1 to the net NH, thereby closing a switch S2 to connect an auxiliary load WH across the rectifier G, and a switch S2<SP>1>, to complete the circuit of a time relay P2. After a further interval, a switch Q2 is closed by the relay P2 and another relay R2 is connected to the net NH to close switches S3 and S3<SP>1>, of which the former connects the ignition device Z and the exciting device E to the rectifier, while the latter completes the circuit of a time, relay P3. After another interval the relay P3 closes a switch Q3' which connects another relay R3 to the net NH, thereby closing the main switch S, in the direct-current net LM. The circuit of the auxiliary load WH is finally opened by a switch S<5>. The main switch S1 may be closed manually, or automatically by means dependent on the current and voltage magnitudes of the entire installation. The auxiliary load WH may be switched in simultaneously with the closing of the main switch S1. For disconnecting the installation both main switches S1, S4 may be disconnected simultaneously on the occurrence of a fault. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the disconnection of the installation by reversing the order of succession of the switches. This subject-matter does not appear in the Specification as accepted.

Patent GB-794419-A (GB)
Title: Process for the removal of heavy liquids from porous catalysts
IPC: B03B5/44
Filed: 1956-04-17
Abstract: Finely divided porous catalysts are freed from liquids which have a specific gravity of above 1.5, and which are immiscible with water, by mixing the catalyst with water.  The volume of water used may be equal to the volume of heavy liquid to be displaced or, for complete removal of the heavy liquid, may be at least equal to the total accessible pore volume of the catalyst. The displaced heavy liquid forms a lower layer which is removed, the upper layer of catalyst and water being treated, if desired, in countercurrent with a water-immiscible volatile solvent, e.g. low boiling hydrocarbons, to remove remaining heavy liquid; water is then removed by filtering or centrifuging and the catalyst is dried by heating.  The catalyst treated may be a powdered synthetic silica-alumina or silica-magnesia cracking catalyst which has been separated into fractions of differing activity and/or selectivity by means of the "sink and float" technique using a liquid organic halogen compound, e.g. dibromoethane, carbon tetrachloride, or bromoform.  In separation processes according to Specifications 648,717 or 761,281, [Group II], using water to fill the pores, the dry particles are first impregnated with the heavy liquid and then treated with water.  The invention may also be used in the separation process according to Specification 794,418, the first stage being a separation in heavy liquid without previous impregnation of the particles with water; this stage is followed by removal of the heavy liquid by treatment with water and then a further separation stage or stages using the heavy liquid.  In an example, dibromo-ethane is removed from cracking catalyst by mixing with water, allowing to settle, and extracting the upper layer with light gasoline.ALSO:Finely divided porous catalysts are freed from liquids which have a specific gravity of about 1.5, and which are immiscible with water, by mixing the catalyst with water (see Group III).

Stencilling-machines; inking-apparatus. - In a rotary duplicator of the kind comprising a rotatable drum carrying an ink-pad and a stencil, clamping-mechanism is provided for clamping the stencil on the drum at its side and trailing edges to prevent excitation of ink. Only the drum is illustrated, and this comprises two end plates 1, with which a perforated diaphragm 3 and an arch-shaped plate 4, Fig. 2, form a sealed inkcontainer. Each end of the usual ink-pad 5 is attached to a perforated metal plate 6, that at the reading end engaging over hooks and that at the trailing end engaging behind a rod 13 with its perforations engaging with hooks 14. The rod 13 is mounted on a block 15 adjustable by means of a screw for tensioning the pad. The leading end of the stencil is perforated to engage studs on the drum and at the trailing end passes over a shoulder 12 at the end of the diaphragm and, together with the ink-pad, is clamped thereagainst. The clamping-device consists of a plate 32 carried by levers 27, Fig. 3, mounted on pivots 25 arranged on pivoted arms 20 fixed in an adjusted position by clamping- studs 23. The arms 27 are moved to and fro by means of manually-actuated toggle links 34, Fig. 2, connected to a rod 30 extending between the levers 27. The arrangement for clamping the side edges of the stencil and ink-pad comprises flanges 44, Fig. 3, carried by plates 41 radially slidable on the end plates 1 of the drum and actuated by rods 40 connected to arms 26 mounted on the pivots 21 of the arms 20. Each arm 26 has lugs 28, 29 so that the lever 27 in its movement actuates the plates 41. A spring 31 maintains a clamping pressure of the plates, and clearance is provided between the lever 27 and the lugs 28, 29 to allow the flanges 44 to seat themselves before the plates 32 clamps the end of the stencil. The plate 32 is weighted by a casting 50, and this weight is counterbalanced by springs 45 pressing the plates 41 outwardly, the arrangement providing that if the drum is rotated with the plates 41 in unclamped positions the weights automatically move them home. An additional clamp for the side edges of the stencil and ink-pad consists of bands 60, Fig. 5, at each side, anchored at one end on pins 61, passed under the flanges 44 and over the plate 32 and fixed to tensioning pegs 62.
